ALVA B. WRIGHT, OF RAMSEY, ILLINOIS.

BUNDLING-MACHINE.

To all whom it may concern Be it known that I, ALVA B. WRIGHT, a citizen of the United States, residing at Ramsey, in the county of Fayette and State oflllinois, have invented certain new and useful Improvements in BundlingMachines and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. y

This invention relates to new and useful improvements in bundling or baling machines and more particularly to a machine for bundling empty cement bags, and the primary object of the invention is to provide a machine or apparatusby means of which empty bags or sacks may be conveniently formed into bundles of suitable sizes and securely held while being tied.

A further object of the invention resides in roviding a machine which may be readily handled by one person to accomplish work which ordinarily requires the efforts of a number of persons, and still another object resides in providing a machine which is simple and durable in construction, inexpensive to manufacture, and one which will be very eiiicient and useful in operation.

"With these and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and pointed out in the specification and claims.

In the accompanying drawings, forming a part of this application: Figure 1 is a plan view of a device constructed in accordance with my invention; Fig. 2 is a side ele vation thereof with the bending bar shown in dotted lines in a position engaged with the locking lugs; Fig. 3 is a similar view showing the bending or engaging arms in their raised positions; Fig. i is anend elevation of the device in the position as shown in Fig. 2; Fig. 5 is a similar view of the device as-disposed and shown in Fig. 3; Fig. 6 is a transverse section through the device as seen on lines 66 of Fig. 3 looking in the direction of the arrows; Fig. 7 is an enlarged detail section through the spaced uprights; and Fig. 8 is a bottom plan view of the device.

In describing the invention, I shall refer Specification of Letters Patent.

Application filed March 12, 1914. Serial No. 824,208.

to the drawings in which similar reference characters designate corresponding parts throughout the several views and in which- 1 indicates a base member which, as shown is of rectangular plate like formation but which, of course, may be of any desired shape and size, as desired, and secured to the under face of the base adjacent the ends thereof, are the supporting leg members 2. Secured to the upper face of this base member 1 at the ends thereof, are pairs of spaced uprights or standards 3, the purpose of whlch Wlll be hereinafter and more partlcularly set forth.

Secured to the upper face of the base 1 immediately adjacent the pairs of standards are the spring bands 4 which project some distance beyond the side edges of said base member, the securing point between said bands and base member being substantially midway of the ends of said bands. Secured to the outer ends of the bands are the bars 5. Also engaged with the upper face of the base member 1 are the flexible members 6 such as linked chains or the like, said chains being engaged with the base member intermediate of their ends and the free ends of said linked chains are secured to the side bars 5 which, as stated, are carried on the outer ends of the spring bands 4. These flexible members or chains 6 are arranged at equal distances from one another between the spring bands 4, and together with said spring bands, form the major portion of the bundling device. It might here be stated also that the spring bands 4 are bowed somewhat downwardly.

In the bundling of the bags, the bars 5 are raised to abut the uprights 3 and I have provided an improved means for accomplishing this result. To this end, the uprights 3 are each slotted transversely as shown at 7 and in the slotted portion of each upright is rotatably mounted a pair of rollers indicated as 8 and 9, the former being disposed just above the latter. pair of flexible members 10 such as cables or the like are provided and disposed through the alining slots 7 of the pairs of uprights 3 to be trained over the upper pulleys 8 therein. Portions of the connections are then disposed inwardly and around the lower pulleys 9, then drawn upwardly through the slots 7 the extreme free ends of said connections being engaged with the or uprights,

side bars 5, as clearly shown in the drawings. From this construction, it will be seen that a portion of each flexible connection 10 is disposed through the space between the pairs of uprights 3 and by forcing downwardly on these portions of the connections toform a loop therein, it is obvious that said side bars will be drawn upwardly toward the uprights 3. For this purpose, I 1 provide a rod orbar 11 which is of a length greater than the length of the base land is adapted to normally reston the portions of: the flexible connections 10 disposed between said pairs of uprights 3. One end of this rod or bar 11 is designed to form a handle as indicated at 12'for the purpose of withdrawii'lg the bar or rod when desired.

Fulcrumed about centrally on the underface of. the base 1 is a lever 13, the fulcrum ointteing disposed adjacent one end of said lever, and engaged with the lever on opposite sides of this fulcrum point, are the additional fleXible connections 14 which extend in opposite directions toward the ends of the base 1.. T hee'nd edges of the base 1 have secured thereto the straps 15 which are looped intermediate of their ends as sh'on 'n at 16 to form bearings for pulleys 17 p and said flexible connections 14; are trained so over said pulleys to permitthe free ends of said connections to project above the plane of the upper face of saidbase. The free ends'of these connections 14 are provided withhooks 18 which are designed for engagement with the rod or bar 11, so that when the lever 18 is actuated in one direction, said rod. or bar may be drawn downwardlytoward the base 1. A ratchet 19 is U also arranged on the under face of the base adjac ent'the fulcrum point of the lever and a sprin detent 20 is provided on the lever for engagement with said ratchet. A handle operating means 21 is provided in connection with the outer end of said lever for the actuation of said detent and as the lever projects outwardly beyond one side edge of the base, the same may be readily applied to use by the operator. In View of the spring detent and ratchet, it will be understood that said lever will be held in any position to which the same is adjusted.

In operation, assuming that the devlce 1s 1n a position ready for operation, a plurality v ofsacks such as cement bags or the like, plled one upon the other, are mounted on the upper face of the base lover the flexible connections or chains 6. The bar 11 is then disposed between the spaced uprights 3 to rest on the portions of the connections 10 disposed therebetween and said bar is then manually forceddownwardly to a pre'deterinedpoint. At this particular point, stop 5 members 22 are provided with which said bar be engaged. It will be understood from the construction of the device, that upon the downward movement of said bar, loops will be formed in the flexible connections 10between the pairs of uprights 3, thus drawing upon said connections and drawing upwardly upon the side bars 5."

l l' ith such movement of said side bars, the flexible connections or chains 6 will be drawn tightly aroundthe sacks or bags disposed 11. lVhen thehooks are thus engaged,the

lever is actuated in the opposite direction from that just mentioned, which operation will obviously draw inwardly upon the connections 14: to cause the rod or bar 11 to be drawn downwardly toward the base 1. Such operation causes the side bars 5 to be drawn farther upwardly toward the uprights 3 and thus tends to roll the bags or sacks on said base member. lVhen the bundle of bags have been rolled to the greatest possible extent capable by' this device, the lever 13 is released, and will be automatically held in such position in view of the spring detent and ratchet. Said bags are then tied securely by hand. The bar 11 is then withdrawn by grasping the handle 12 thereof v and drawing outwardly thereon. The lever may be released and the tied bundle of bags readily removed from the device. The device is then ready for operation in connection with another set of sacks or bags.

From the foregoing, it will be seen that I have provided a simple, inexpensive, and eflicientv means for carrying out the objects of the invention, and while I have particularly described the elements best adapted to perform the functions set forth, it is ob vious that various changes in form, proportion and in the minor details of construction may be resorted to,within the scope of the appended claims, without departing from the spirit or sacrificing any of the principles of the invention.
